Hi Nick,
Always fast with support, thanks.
That did the trick.....This was the problem indeed.....this is the first time this happens to me...i wonder how come? (i didn't switch it off)
After switching it back on, the whole scenery and atmosphere improved, grass, RWY, Taxiways and city are fine !
Sorry for my mistrust....and thanks again for offering the solution right away.
Regards,
Ben
